One sweltering day, I was scooping ice cream into cones and told my four children
they could "buy" a cone from me for a hug. Almost immediately, the
kids lined up to make their purchases. The three youngest each gave me a quick
hug, grabbed their cones and raced back outside. But when my teen-age son at
the end of the line finally got his turn to "buy" his ice cream, he
gave me two hugs. "Keep the changes," he said with a smile.
